The emphasis of guidance on analytic methods for the economics components of Cochrane reviews is upon tabulation of the characteristics and results of included health economics studies. This can be supplemented by a narrative summary which focuses on critical appraisal of included studies and discussion of their principal findings. Additionally, in some circumstances, a meta-analysis of resource use or cost data, or development of an economic model, may be considered. These options are described in more detail in the sections that follow. Further options for analysing health economics studies and presenting the results of these analyses need to be evaluated through further methodological research (see Section 15.9).
